阿里云api实现ipv6的ddns

创建python的虚拟环境

# 创建一个虚拟环境python3 -m venv ipv6_py_env# 激活虚拟环境source ipv6_py_env/bin/activate

获取ipv6地址的脚本

ifconfig | grep -A 10 wlp2s0 | grep 'inet6' | awk '{print $2}' | sed '/fe80/ d'

将上述脚本使用python封装

res = sp.run("ifconfig | grep -A 10 wlp2s0 | grep 'inet6' | awk '{print $2}' | sed '/fe80/ d'", shell=True, capture_output=True, encoding="utf8")ipv6_addrs = res.stdout.split()  # ipv6地址可能有多个，随便用一个即可

最后执行该文件即可

python auto_refresh_dns.py

参考：

https://next.api.aliyun.com/api/Alidns/2015-01-09/UpdateDomainRecord

上面的api需要传入 RecordId，可以通过下面的api获取

https://next.api.aliyun.com/api/Alidns/2015-01-09/DescribeDomainRecords

ALIBABA_CLOUD_ACCESS_KEY_ID 和 ALIBABA_CLOUD_ACCESS_KEY_SECRET 在阿里云控制台可查看
